This article discusses, at a simple level, the dynamics of the wheel-rail interface, which is fundamental to the stability of rail vehicles. The physics underlying this topic deserves to be better known by physicists and physics students, as it underpins such an important part of our technological infrastructure

The 1969 version of "The Italian Job" is used as context for teaching turning forces and introducing or enhancing the understanding of equilibrium and Newton's Third Law of Motion. A Harrington Legionnaire coach is used as the getaway vehicle for a gold heist and the film ends on a genuine cliffhanger, with the rear half of the coach…

This study investigates the modelling conceptualisation of secondary school students in two situations related to particle dynamics: pendulum's motion and horizontal motion. We performed in-depth clinical interviews with secondary school students (N = 10). Participants' ideas about properties which are not 'given' in empirical observations were…

Ongoing changes in mental and personal characteristics of the modern child initiate the updating of means and forms of education. And they, in their turn, update methodological techniques and approaches to the use of methods during the math class. The source of updating methodological techniques may be the principles used when solving scientific…

Linguistic diversity in many schools is high such that science teachers face complex issues regarding appropriate ways of mediating social and academic language in multilingual classrooms. The relationship between these aspects and the task of teaching science (i.e., pedagogy) remains a mystery to many teachers. This paper provides a narrative and…

Evolutionary evidence is important scientific background for appreciating the theory of evolution. We describe a STEAM-based lesson plan that uses paleontological drawings and a modern evolutionary database to explore and understand fossil, morphological, and molecular evidence. Together, with a focus on arthropods and the Cambrian explosion,…

Science appears to be coming under increasing pressure in parts of society and the media, with an increase in 'fake news' and less regard for 'experts'. If this is to be combatted, it is important that students develop a good understanding of both the big conceptual ideas of science and the nature of science itself. This understanding will mean…

This study aims to investigate textbook tasks in the Norwegian school subject Natural sciences and the views of science that the tasks mediate to the pupils. Natural science is an interdisciplinary subject taught in Years 1-11 that includes chemistry, physics, biology and parts of the geosciences. We conducted a qualitative content analysis of…

The authors conducted a qualitative content analysis of the 400 National Science Teachers Association Outstanding Science Trade Books for Students K-12 from 2010-2017 selected for their instructional usefulness in science classrooms. The authors examined these expert-recommended science trade books to better understand their design and to identify…

Research on nature of science (NOS) has confirmed that students' understanding of NOS is best achieved by explicitly considering NOS a cognitive learning expectation and providing opportunities to reflect on it. However, little has been discussed on how to design and use tasks enhancing students' NOS understanding. In an attempt to fill this gap,…

The phenomenon of lateral inversion is explored in this question. If a clock is viewed in a plane mirror, will the motion be clockwise or anticlockwise?

Physics students often have problems understanding waves. Over the years numerous mechanical devices have been devised to show the propagation of both transverse and longitudinal waves (Ref. 1). In this article an updated version of an early-20th-century transverse wave machine is discussed. The original, Fig. 1, is at Creighton University in…

The French utopian socialist Charles Fourier is a key figure in Walter Benjamin's "Arcades Project". For Benjamin, one of the most significant aspects of Fourier's utopian vision was its conceptualisation of work as a form of play. According to Fourier it would be possible to build a world around people's inherent desires. In such a…

In this article we reviewed the main concepts of detonative combustion. Concepts of slow and fast combustion, of detonation adiabat are introduced. Landmark works on experimental and semi-empirical detonation study are presented. We reviewed Chapman-Jouguet stationary detonation and spin detonation. Various mathematical model of detonation wave…

The word "wave" is part of the daily language of every student. However, the physical understanding of the concept demands a high level of abstract thought. In physics, waves are oscillating variations of a physical quantity that involve the transfer of energy from one point to another, without displacement of matter. A wave can be…
